Hello,
The attached patch adds support for the following Eon SPI flash chips: EN25Q40, EN25Q80, EN25Q32A/B, EN25Q64, and EN25Q128
I was going to add support for the EN25Q16 as well, but found that it shares the same ID as the EN25D16 but has different write protection capabilities. So I added a comment instead.
I do not have real hardware to test with at the moment, so I left the status as untested.
